Antigua and Barbuda Generator Buying Guide and Tips

• Right size, right circuit: Add up essential loads (fridge, lights, router, pump). Homes often cope on 2–3 kW inverters; villas or businesses may need 5–15 kW or diesel gensets.
• Noise matters: Inverters are 50–60 dB at 7 m; open-frame petrol sets can exceed 70–85 dB. Be mindful of neighbours.
• Fuel choice: Petrol for portability/short outages; diesel for long runs and efficiency; LPG dual-fuel can simplify storage.
• Electrical safety: Always use a licensed electrician for changeover/ATS installation—never back-feed APUA lines.
• Power quality: Protect sensitive devices with pure-sine inverter generators and surge protection.
• Cords & outlets: Use 230 V-rated Type G cords (10–12 AWG equivalent). Keep them dry and short as possible.
• Maintenance: First oil change early (5–20 hrs), then follow service intervals. Keep spare filters, plugs, and oil handy.
• Weather & storage: Tropical humidity requires covered, ventilated placement; consider a running cover or corrosion-resistant enclosure.

Buying Generator in Antigua and Barbuda FAQs

How much does generator installation usually cost in Antigua and Barbuda?
For portable units with manual changeover, budget around XCD $1,000–$3,500 for electrician labour and materials. A standby diesel system with ATS and cabling can run XCD $7,000–$20,000+ depending on project scope (excluding generator cost).

How noisy can a generator be in Antigua and Barbuda?
Inverter generators are typically 50–60 dB @ 7 m (like a normal conversation). Open-frame petrol units run 70–85 dB, and enclosed diesel gensets ~65–75 dB. Always consider neighbours and local noise rules.

Which generator type and fuel are best for Antigua and Barbuda’s climate?
For occasional outages: petrol inverters (quiet, portable). For frequent or prolonged outages: diesel standby systems—better efficiency and longevity in hot, humid conditions.

What are the typical warranties for generators in Antigua and Barbuda?
Portable units usually carry 1–2 year limited warranties. Diesel standby/prime gensets often come with 12–24 months or hour-based coverage when installed and serviced by an authorised dealer—always confirm in writing.
